Hi everyone,
I'm new to kamailio and rtpproxy and the problem's been bothering me for
days. Any help would highly appreciated.
My network topology is as follows:
kamailio5.0 and rtpproxy2.0 are running on the same server. The server is behind
NAT, its private ip is 10.240.0.62, public ip is <PUBLICIP>
the server has 5060 tcp&udp, 35000-65000 udp port enabled.
There're 2 sip clients(test && test1) running in another
LAN(175.100.202.xxx) .
Situation:
Both clients registered successfully and they can call each other. But neither of
them has audio.(If i kill rtpproxy, audio is ok).
My kamailio cfg(only posted the part that i change),
#!KAMAILIO
#!define WITH_MYSQL
#!define WITH_DEBUG
#!define WITH_AUTH
#!define WITH_USRLOCDB
#!define WITH_ANTIFLOOD
#!define WITH_NAT
#!define WITH_PSTN
listen=udp:10.240.0.62:5060 advertise <PUBLICIP>:5060
modparam("rtpproxy", "rtpproxy_sock",
"udp:10.240.0.62:64000")
rtpproxy cmd:
rtpproxy -A <PUBLICIP> -F -l 10.240.0.62 -m 35000 -M 65000 -s udp:*:64000 -d INFO
I used ngrep -d any -qt -W byline port 5060 to capture the sip msg, they are as
follows:
